Local unwinding during replication results in overwinding or supercoiling of surrounding regions

DNA topology. Local unwinding during replication results in overwinding or supercoiling of surrounding regions. From the field of topology: twist (Tw) = # of dsDNA turns writhe (Wr) = # of times the helix turns on itself linking number (Lk) = sum of twist and writhe. Lk = Tw + Wr.
